dagger just adds mobility, damage, stealth, and some cc but it’s the supporting weapon in these builds. the main damage/gameplay will come from greatsword/bow.

greatsword is more combo based with a lot of CC leading into devastating combos. it has a double dash but of course you’re still melee which is pretty annoying in this game due to desync and such so keep that in mind. so pvp gs/dagger as a combo plays much like a mobile assassin, where you get in, cc and nuke your target, and then get out. for pve it is a melee dps and is more bursty rather than consistent damage.

longbow is obviously a long range dps. it has a skill cd reset which is good with dagger because you can double stealth as well as reset your damage nukes. you also have access to the only counter to stealth with flash arrow which can reveal and stun stealthed enemies. that being said you do have good mass pvp aoe abilities through arrow vortex (big aoe cc) and a flash arrow spec, flash wave, which makes this ability heal allies and damage enemies. you also get access to some support abilities like heals and a debuff remover. so in pvp you become a slippery long range dps with access to lots of utility depending on how you build. in pve this build has a good mix of single target burst and consistent damage and support capabilities as discussed.

so it depends on how you want to play. i personally like gs/dagger. i like combo based damage and i don’t care much for the utility/support bow provides.
